I'd also try to keep the ducks out of the pond too.
Yup, I know and have been thinking about that, lol. It's going to take some work to figure out a way in which I can allow them some space to roam, have an artificial water source but keep them out of the pond. Or as this flock finally succumbs fully to the critters, I could forgo replacing them and go strictly with chickens. We love our ducks though. They have been very personable pets and they lay well.
